Enhancements
Update to Arnold 5.1.1.1: The latest Arnold bugfix release is bundled, with some important bug fixes.
- Optionally disable XGen multithreading: As a workaround for some occasional XGen issues, multithreading can be turned off in ArnoldXGen. This should only be done when necessary, as it has a performance impact. (#302)
- EXR layer name override: Layer names in EXRs normally end up with the generic channels R,G,B,A, but using the EXR and deep EXR driver
preserve_layer_name
it will use the name of the AOV as set inArnoldOutputChannelDefine
. However, the layer name can now be further customized withlayerName
, when used in conjunction withpreserve_layer_name
. (#305) - Curve orientations attributes: Curve per-control-point orientation vectors can now also be specified with
geometry.point.N
andgeometry.point.normal
in addition to thegeometry.point.orientation
that was already supported. (#306)
